How to differentiate terms involving surds by expressing with fractional index e.g. y = 10√x

Surds should be expressed using a fractional index/exponent before differentiating.

Derivatives involving fractional indices should be expressed in surd form.

The convention is that if the original function uses a fractional index, the derivative may be expressed using a fractional index. If the original function is in surd form, then the derivative should also be in surd form.
